Two of three people killed in a mass shooting at Chicago's Gage Park neighborhood have been identified, according to the Cook County Medical Examiner's office.
The victims -- a 28-year-old and a 26-year-old man, who were among eight people shot inside a home on Chicago's Southwest Side -- were identified as Jon Carlos Blancarcer and Hector Sajo, respectively.
A third person killed in the shooting has not yet been identified.
The eight victims ranged in age between 20 and 35 years old, authorities said.
The shooting was reported at around 2:10 p.m. Monday near West 59th Street and South St. Louis Avenue, but several questions surrounding what happened remain unanswered hours after the incident.
According to authorities, all eight victims were at a gathering inside a home in the 3500 block of West 59th Street.
Officers responded to a call of a person shot in the area and discovered four men and four women had been shot, said Chicago Police Department Chief of Patrol John Hein.
